ES PAGNOLETTE-LOCK.

SPECIFICATION formingpart of Letters Patent No. 695,620, dated March 18, 1902.

Application filed May 17,1901. Serial No. 60,751. (No model.)

I ating-handle midway the frame and clamping-hooks locking above and below the sash are known to the art; but the following invention provides means for locking tightly both above and below and simultaneously midway the sash and also at any desired point or points in the frame, and, further, the means so employed when locked automatically hold themselves in the locked position, thus firmly holding the sash in position.

In the accompanying drawings, in which similar letters of reference refer throughout to similar parts, Figure 1 illustrates a partial front view of a window the sashes of which are provided with a lock embracing the present invention in a closed position. Fig. 2 is a horizontal sectional view of Fig. 1. Fig. 3 is a side elevation of Fig. 1. Fig. 4.- represents in side view the look when open. Fig. 5 illustrates a modification. Figs. 6 and 7 are front and cross-section views,respectively, of a modified lock closed as used with singlesash windows. Fig. 8 is a side view of Fig. 6.

In the construction of my invention I employ the usual Spanish sash bolt or rod a, which is rotatably journaled vertically in suitable eyes or bearings i z, mounted on one of the sashes and adjacent to the adjacent sash when the window is closed. Said rod a is bent right-angularly near its upper and lower ends and has hooks in is formed on its ends so bent. Studs Z Z, mounted on the frame of with a perforated shoulder, through which lat-- and 4.) Said lever is split or forked, so that its prongs ride on either side of said shoulder.

These prongs or noses e and f are eccentrically formed and of different lengths (see Fig. 2) and when lever dis pushed downwardly into a locked position engage plates 9 and h, respectively, fastened on the sashes n and m. It is obvious that when the lever is so snapped to that nose f, riding behind rod 0., prevents the rotating of the latter until the lever is again properly raised. It is further obvious that the said noses press firmly against the sashes and hold the latter substantially locked. If desired, any suitable number of collars may be mounted on the rod a, together with suitable plates p on the other sash,'so that, especially if the window-sash in question be of extraordinary dimensions, firm locking devices are hereby provided at any desired interval. (See Fig. 5.)

The lock described is equally applicable for single-sash swinging windows; but for sake of brevity I have shown a modified form in connection with such a window, as illustrated in Figs. 6 to 8, inclusive. Here it will be seen that lever (Z is provided on one side with a nose g, which is adapted to be swung from below up under and engage a hook s, fastened to the frame r. This form is also equally applicable to double-sash windows.

The operation of the lock is obvious. ver d is swung upwardly, carrying its camformed noses e and f free of their plates and the sashes, so that rod or can be turned. The
